Biometrics

INTRODUCTION

✴ The term “biometrics” is derived from the Greek words “bio” (life) and “metrics” (to measure).✴ Biometrics is the technical term for body measurements and calculations.✴ Biometrics is the measurement and statistical analysis of people’s unique physical and behavioral characteristics.✴ Biometrics allows a person to be identified and authenticated based on a set of recognizable and verifiable data, which are unique and specific to them.✴ Biometrics authentication is the process of comparing data for the person’s characteristics in order to determine resemblance.

TYPES OF BIOMETRICS

Biometrics Can Be Divided Into Three Main Categories Of Characteristics:1. BIOLOGICAL2. MORPHOLOGICAL3. BEHAVIORAL

⏩DNA MATCHING

The identification of an individual using the analysis of segments from DNA.

👂EAR

The identification of an individual using the shape of the ear.

👀EYES – IRIS RECOGNITION & RETINA RECOGNITION

👁IRIS RECOGNITION- The use of the features found in the iris to identify an individual.👁RETINA RECOGNITION- The use of patterns of veins in the back of the eye to accomplish recognition.

👱‍♂️FACE RECOGNITION

The analysis of facial features or patterns for the authentication or recognition of an individuals identity.

🤘FINGERPRINT RECOGNITION

The use of the ridges and valleys (minutiae) found on the surface tips of a human finger to identify an individual.

👋FINGER GEOMETRY RECOGNITION

The use of 3D geometry of the finger to determine identity.

🤚HAND GEOMETRY RECOGNITION

The use of the geometric features of the hand such as the lengths of fingers and the width of the hand to identify an individual.

🙌VEIN RECOGNITION

Vein recognition is a type of biometrics that can be used to identify individuals based on the vein patterns in the human finger or palm.

👩‍💻TYPING RECOGNITION

🗣VOICE / SPEAKER RECOGNITION

There are two major applications of speaker recognition:🙊Voice – Speaker Verification / Authentication🙊Voice – Speaker Identification✔In forensic applications, it is common to first perform a speaker identification process to create a list of “best matches” and then perform a series of verification processes to determine a conclusive match.✔Voice recognition analyzes audio input for specific patterns in speech or sound. Each voice, or common noise, has a recognizable wavelength pattern that can aid in identification of a specific individual.

🚶‍♀️👣GAIT

The use of an individuals walking style or gait to determine identity.
